Define: System

A set of interacting parts forming a complex whole.

100

What type of rock forms from heat and lots of pressure?

Metamorphic Rock

100

All of Earth’s energy comes from either…

  • The sun

  • Earth’s interior

100

Why does Wisconsin not have earthquakes or volcanoes?

Because Wisconsin falls in the middle of a plate not on a plate boundary.

200

Define: Sediment

Small, solid pieces of material that come from rocks or living things.

What part of the Earth fits this description?

CONSTANTLY BEING BROKEN DOWN AND REFORMED. INCLUDES CONTINENTAL AND OCEANIC CRUSTS. SEPARATED INTO INDIVIDUAL PLATES

Crust

200

At a plate boundary, one is sinking below the other. What type of plate boundary must this be?

Convergent (continental-oceanic) boundary

300

Define: Crystallization

The process by which atoms form a crystal arrangement as they cool and lose kinetic energy. 

300

What type of rock fits this description?

Found at divergent boundaries, like mid-ocean ridges, plates drift apart and form gaps that are filled by magma.

Igneous

300

What part of the Earth fits this description?

SOLID (BUT SOFT) ROCK. ALTHOUGH VERY HOT, PRESSURE KEEPS IT SOLID, SLOWLY FLOWS

Mantle

300

What plate is the oldest? Why?


Plate B: It is more dense than plate A. Its more dense due to cooling.

400

Define: metamorphic rock 

A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions. 

400

What type of rock is this? 

Metamorphic

400

Earth's tectonic plates are moving and therefore have ______ energy, which can be traced back to energy from ______.

kinetic; Earth's interior

400

What is the movement of plates powered by?

Geothermal energy.

500

Define: Weathering 

The breaking down of rocks and other materials on the Earth's surface.

500

What rock type is this?

Sedimentary.

500

Describe how both the sun and the  Earth's interior power the rock cycle.

Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust and the movement of water, ice, and air at the surface, and is powered by the sun.

500

What is the Plate Tectonic Theory?

Plate Tectonic Theory – the Earth's solid outer crust is separated into plates that “float” around on the upper mantle
